An orphaned baby otter found stranded at a San Mateo County beach in September is now living at a Chicago aquarium where it is receiving round-the-clock care and learning how to be an otter, aquarium officials said.

As Harbor pup seals are now being born on Bay Area beaches, beachgoers are reminded to stay away from newborn pups even if they are concerned that the pup may be orphaned, officials at the National Oceanic and Atmospheric Administration said.

Having already set a milestone for birthing a pup after being found covered in oil, a sea otter gave birth to a second pup this week, a California Department of Fish and Wildlife spokesman said Thursday.
